5) Assign the peaks in the 'H NMR spectrum of your product. Draw your structure on the NMR spectrum and label each set of inequivalent protons. Use these labels in assigning the peaks. In some cases the aromatic peaks may overlap, so it is OK to assign groups of protons to a series of overlapping peaks if necessary. Try to be as specific as possible in your assignment, though. Discuss in detail how the NMR spectrum is only consistent with...

Analyze the peaks in this NMR spectrum of p-nitrophenol
assigning the peaks, discuss multiplicity, splitting,
shielding/deshielding effects, and integration.
I have assigned the peaks but i am not sure if i have done it
correctly. Is there expected to a peak for the -OH? or is there not
a peak because the proton is exchangeable? is there complex or
normal splitting observed?
